How can I tell if my 1968 911L is US or Euro spec

Hey all,

After months of searching and researching, I just picked up my first barn find; a '68 911L, and am starting the restoration process.

In doing so, I was trying to determine if my 911L is US Spec or Euro Spec.

I know that the VIN decoder for my 8-digit VIN essentially consists of the following:
1181XXXX
Digits #1 and #2: 11 (meaning 911)
Digit #3: 8 (meaning 1968 model year)
Digit #4: 1 (meaning 911L coupe)

As a note, here was my reference:
Porsche VIN decoder - Stuttcars.com

The reason I ask is that I received the following initial sales receipt and it's shown in Francs.

Also, I received the following original sales documents which are noted to be in German:
- Pflegepass (appropriate care booklet)
- Kraftfahrzeugbrief (motor vehicle letter - which I understand is a sort of registration document)
- Verwahrungsschein fur den Fahrzeughalter (Title transfer, I believe)

Any help would be greatly appreciated!

Cheers.
